    Isonicotinic acid hydrazide (INAH) affords its acetoacetate (IV), when reacted with diketene. IV gives isonicotinopiperidide and 3-methyl-2-pyrazolin-5-one (VII) in the presence of piperidine in ethanol solution, and it also produces VII and isonicotinc acid in the presence of pyridine in acetic acid solution. IV affords INAH and 1-phenyl-3-methyl-2-pyrazolin-5-one (II), when reacted with phersylhydrazine and it also produces VII and 1, 1-diisonicotinoylhydrazine (VIII) in the reaction with INAH. However the cyclization reaction of isonicotinoylpyrazolone (V or VI) was unsuccessful. IV is hydrolyzed into VIII, VII and acetone, emitting carbon dioxide gas. On the other hand, the hydrolysis of IV, after the benzylation, gave 3-methyl-4-benzyl-2-pyrazolin-5-one and isonicotinic acid. The reaction mechanisms is discussed in this report.

    Based upon the fact that 7-amino-3, 6-dimethylpyrazoio[1, 5-a]pyrimidirie (XIII) possesses effective antipyretic and analgetic action, 14 methyl substitutes of 7-aminopyrazolo[1, 5-a]-pyrimidine in its nuclei were synthesized.
    With 5-aminopyrazoles (VII-X), 2-methyl-3-ethoxy-3-methoxypropionitrile (I) was reacted to give 6-methyl compounds (XI-XIV), acetoacetonitrile (III) was reacted to give 5-methyl derivatives (XV-XVIII), 2-acetopropionitrile (IV) to 5, 6-dimethyl derivatives (XIX-XXII), and ethyl ethoxymethylenecyanoacetate (V) to 6-ethoxycarbonyl derivatives (XXVII-XXX). In this connection, the cyclization with V in both acidic and alkaline media, and the saponification of XXVII-XXX were investigated. The thermal decomposition of XXXV-XXXVIII produced decarboxyl compounds (XXXIX-XLII) easily. Another synthetic method of XLII was also studied.

    In order to reduce the side effect of N-phenylacetylureas, hitherto used as anticonvulsants, 1-acyl-3-phenylacetylureas were prepared by acylation of N-phenylacetylureas or by the reaction of acylisocyanates and acylamides. Of the compounds synthesized, 1-acetyl-3-(1-ethylphenylacetyl)urea was found to be a convulsant with small side effect.

    The structure of trilobine was reported by Inubushi and Nomura as the formula (I) from the cleavage reaction of its N-acetyl compound with metallic sodium in liquid ammonia. The antipodal isotrilobine (II) was synthesized from dlhydroepistephanine (V) by the present writers.
    In the present series of work, O-methylanhydrodemethyl-N-ethyl-dihydroepistephanine (X) was synthesized from N-ethyldihydroepistephanine (VII) by a similar method. X came as a picrate of m.p. 194-195°, [α]D-283.1° (acetone), C37H38O5N2⋅2C6H3O7N3⋅1 1/2H2O. By comparison with the picrate, m.p. 193-195°, [α]D+283.8° (acetone), C37H38O5N2⋅2C6H3O7N3⋅1 1/2H2O, of the N-ethyl compound (III) from natural trilobine (I), X was found to be its antipode (cf. Table I). Consequently, the structure of trilobine was reaffirmed as I by synthesis.

    Distribution coefficients of isonicotinoylhydrazone (isoniazone) of calcium pyruvate, sodium pyruvate, glucose, and sodium glucuronate between isoamyl acetate and water at 30° were determined by considering the hydrolysis equilibria of the isoniazones in both phases. For this purpose, the concentrations of INAH, isoniazones, and carbonyl compounds were measured in the aqueous and oil layers, and the distribution coefficient of each component and the equilibrium constant of the hydrolysis in both layers were calculated. It was found that the isoniazones may be classified into three types on the basis of oil/water distribution characteristics and that the calculated equilibrium constants of hydrolysis reaction in the aqueous layer coincide well with the directly measured values in aqueous solution. The distribution of isoniazone itself is so poor that the antitubercular activity of isoniazones seems to be mainly due to INAH produced by the hydrolysis reaction.

    Examinations were made on the analgesic and related pharmacological action of 1, 4-bis[(2-methoxy-4-propylphenoxy)acetyl] piperazine (AP-2). Its analgesic action is equal to that of codeine phosphate by the pressure method and about one-half of that by the D'Amour-Smith method, being over 4 times that of sulpyrine. This analgesic action of AP-2 is not antagonized by nalorphine. Acute toxicity is low and there is no effect on the growth, fertility, blood picture, or tissue pattern of the organs by longterm administration. AP-2 markedly lowers the body temperature of albino rats and its antipyretic action on febrile rabbit is slightly stronger than that of sulpyrine. AP-2 has 1/2 to 1/4 of the antiphlogistic action of anlinopyrine and shows suppressive action of long duration on dextran edema and egg-white edema. It is synergistic with the hypnotic action of methylhexabital but has weak action of extending sleep. AP-2 does not antagonize convulsion caused by convulsion-producing agent.

    In the presence of chloramine T, the reaction between 2, 4-dinitrophenylhydrazine, and α-, β-naphthol in acidic solution afforded the corresponding products. α-Naphthol gave red needles, m. p. 277.5°(decomp.), which showed yellowish orange coloration (λmax 460mμ) in acidic solution and blue coloration (λmax 640mμ) in alkaline medium, which is reversible of having isosbestic point at 508 mμ. The elemental analysis, UV and IR spectra of the crystals are quite identical with 4-(2, 4-dinitrophenylazo)-1-naphthol which was synthesized from the reactions of α-naphthoquinone and 2, 4-dinitrophenylhydrazine or of α-naphthol and 2, 4-dinitrophenyldiazoniumsulfate. On the other hand, β-naphthol gave reddish orange needles, m. p. 305.5°(decomp.), showing orange-yellow coloration (λmax 480mμ) in acidic solution and blue (λmax 600mμ) in alkaline medium. This coloration is reversible of having isosbestic point at 522mμ. The elemental analysis, UV and IR spectra are identical with 1-(2, 4-dinitrophenylazo)-2-naphthol which was synthesized from β-naphthol and 2, 4-dinitrophenyldiazoniumsulfate but was not identical with 2-(2, 4-dinitrophenylazo)-1-naphthol which was synthesized from β-naphthoquinone and 2, 4-dinitrophenylhydrazine. Therefore, the products in this reaction were found to be 4-(2, 4-dinitrophenylazo)-1-naphthol in the case of α-naphthol and 1-(2, 4-dinitrophenylazo)-2-naphthol from β-naphthol.

    Application of oxalyl chloride to 5-methoxyindole gave 5-methoxyindole-3-glyoxylyl chloride as orange-red crystals, m. p. 134°(decomp.), and application of ammonia to this chloride afforded 5-methoxyindole-3-glyoxylamide as yellow plates, m. p. 248°. The yield was almost quantitative in both reactions. Reduction of this amide with lithium aluminum hydride in a mixture of tetrahydrofuran and ether gave 5-methoxytryptamine in a good yield. Condensation of 5-methoxytryptamine and phenyl acetate by heating in tetraline or α-methylnaphthalene at 160-180° for 2 hours resulted in the formation of melatonin, obtained by Lerner and collaborators from ox pineal gland. The synthetic melatonin, obtained in a good yield, came as pale yellow leaflets, m. p. 116°, and its solution exhibited a marked yellowish green fluorescence. This substance shows absorption maximum at 277.5mμ in its ultraviolet spectrum and exhibits green by Keller's reaction and violet by van Urk's reaction, which are the specific color reactions of tryptamine series compounds.

    Octahalodibenzo-p-dioxin (VII) and (VIII), synthesized earlier, are negative to the dibenzo-p-dioxin reaction using conc. sulfuric acid and potassium nitrate or other oxidation agents. In order to examine whether this negative coloration is due substitution of all hydrogen atoms in the benzene ring of the octahalo derivatives with halogen atoms or to insolubility of such substance in conc. sulfuric acid, 4, 9-diethyl-1, 2, 3, 6, 7, 8-hexamethoxydibenzo-p-dioxin (IX) was synthesized and its dibenzo-p-dioxin reaction was examined. In the present series of work, octamethyldibenzo-p-dioxin (V) was synthesized by the route shown in Chart 1 and this compound was found to color blue to conc. sulfuric acid and potassium nitrate. This has shown that the presence or absence of hydrogen atoms in the dibenzo-p-dioxin skeleton does not affect the dibenzo-p-dioxin reaction.

    When 1-nitroso-2-naphthol and potassium nitrate were reacted with morphine in acetic acid medium in the presence of a trace of sodium nitrite, a stable coloration was observed. This reaction was adopted to the colorlmetric determination of morphine. Morphine is able to be determined without any influence, even if five times as much codeine, thebaine, narcotine and papaverine as morphine exist, but meconic acid present in opium disturbs the determination in not less than the equi-amount.
    Manipulation: one ml. of the sample (morphine hydrochloride, anhydrous, 50-400μg/ml.) was taken into 10ml. graduated cylinder, 5ml. of 60mg.% of 1-nitroso-2-naphthol in acetic acid and 2ml. of 10% potassium nitrate were added and maintain at 25° for 10 min. Then, one ml. of 20mg.% sodium nitrite was added, water was later added to make 10ml. It was shaken well and kept standing at 25° for 60 min. The optical density was measured at 530mμ. The optical density was measured at 530mμ. The blank was made with water, instead of the sample.

    The colorimetric determination of oxymorphone hydrochloride with 1-nitroso-2-naphthol and potassium nitrate was examined. As an acidic reagent hydrochloric acid was preferable instead of acetic acid used in the determination of morphine. This method follows the Beer's law within the concentration of 50-300μg./ml., and an accuracy of the measurement was σ=0.58% (n=6).
    Manipulation: To one ml. of the sample (contains 50-300μg./ml., as an anhydrous oxymorphine hydrochloride), 0.5ml. of 0.04% 1-nitroso-2-naphthol was shaken and 2ml. of 15% hydrochloric acid and 1ml. of sodium nitrate added 30% potassium nitrate (0.01% sodium nitrate 0.6ml.+30% potassium nitrate 100ml.) were added. It was maintained at 25° for 10 min. Later, water was added to make 5ml. and the optical density was measured at 530mμ.
